Good call.

That's the immediately obvious solution, but it doesn't actually fulfill
the problem requirements. What if your last line is less than 60
characters long? You no longer will be displaying the input in reverse
order. Otherwise you'd be right - my solution would be unnecessarily
unwieldy (and the problem would be much simpler...) .
